BACKGROUND OF THE INVENTION

The present invention relates to a computer, and more particularly to acomputer for a reproducing medium having a function for indicatingrelated information of the reproducing medium.

Recently, various types of information reproducing media using CD(compact disc) media come into the market. The CD was generally used asa CD audio disc at first. Nowadays, the CD-ROM is popular mainly for acomputer. The CD-ROM includes the photo-CD, enhanced music CD(hereinafter called CD-extra) and video-CD. Particularly, the CD-extraand photo-CD are also included in the multisession CD having a pluralityof sessions. In each session, a lead-in area and a lead-out area areprovided.

Furthermore, recently, the personal computer has been improved to havereproducing programs for reproducing not only the photo-CD and video-CD,but also have reproducing programs for the CD-Audio so as to reproducethe music CD.

On the other hand, the personal computer has come to be communicatedwith external equipments through networks for easily exchanginginformation each other. For example, in the Internet, a user activates abrowser and input an address of a server which has desired informationso as to freely access the server.

There is a server having a function to retrieve the address by akeyword. Therefore, even if a desired address is not known directly, ifthe user accesses the server having the retrieval function, the desiredaddress can be obtained indirectly by the server.

For a high speed process, it is possible to activate a plurality ofprograms in time sharing and operate a plurality of functions inparallel. For example, a reproducing program and a browser program of amusic CD are activated in parallel, and the music CD is played, whilerelated information of the music CD such as title of the CD, name ofmusic can be displayed on a display.

However, in this case, first the user must presume one of keywords ofthe related information such as a name of singer of the music CD to beplayed, and operate to activate the browser of the personal computer bythe presumed keyword, thereby obtaining an address of the relatedinformation from the server having the retrieval function. Therefore,the related information is obtained by the address. Thus, a problem thata complicated operation is needed arise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, a computer 1 for a CD player according to thepresent invention has functions for automatically activating areproducing program of a CD 8 set in the player and automaticallycalling related information of the CD.

The computer 1 comprises a controller 2, a reading section 7 for readinginformation recorded on the CD 8, an input unit 9 for manually inputtinginformation, and a display 10 for displaying the information. Thecontroller 2 has control programs at least such as an automaticactivation program for automatically activating a reproducing programcorresponding to the type of CD, a selection information decidingprogram for deciding priority reproduction of a session of the CD-extra,and an automatic calling program for automatically calling the relatedinformation of the CD. The reading section 7 has a hardware such as apickup, and a driver for driving the pickup.

Furthermore, a plurality of programs such as CD-Audio reproducingprogram 3, photo-CD reproducing program 4 and video-CD reproducingprogram 5, a RAM 6 for storing the selection information and a CD-ROMreproducing program, and a database 18 having a retrieval table 18 a areprovided in the computer 1.

These elements are connected to each other through a bus-line 11. Thebus-line 11 is further connected to an external communication channel 12which is connected to servers 13, 14, 15 and 20.

Various operations of the computer 1 will be described hereinafter.

First, an automatic activating function of the reproducing program willbe described with reference to the flowchart of FIG. 2. Such a functionis operated by the automatic activating program of the controller 2.

At a step S1, when the CD 8 is set in the CD player, the controller 2controls the reading section 7 to drive the CD 8 and read information(TOC information) recorded on a lead-in area of a first session(innermost session). Thus, the driver of the reading section 7 isoperated to drive the pickup and motor to read the TOC information. Theread information is produced.

At a step S2, the information such as control bit, address bit, minute,second, and frame number is obtained from the TOC information. Thecontrol bit is used to identify whether the first session is the one ofa CD-Audio or the one of a CD-ROM. The address bit is used to identifywhether the CD 8 has a single session (namely, only a first session isprovided) or a multi-session such as CD-extra.

At a step S3, the value of address bit is detected, and it is determinedwhether the CD 8 has the single session or the multisession by theaddress bit. If the CD 8 has the multisession, the program goes to astep S4. If the CD 8 has the single session, the program goes to a stepS5.

At the step S4, since a start time of the next session is obtained bythe TOC information, a lead-in area of a second session of the CD isread by the reading section 7. The program returns to steps S2 and S3.Thereafter, steps S4, S2 and S3 are repeated until the last session isread, and the program goes to the step S5.

The type of CD 8 is determined in accordance with the information ineach session as described hereinafter.

At the step S5, it is determined whether the CD 8 is the CD-Audio or theCD-ROM by the control bit in the TOC. If the CD 8 is the CD-Audio, theprogram goes to a step S6. If the CD 8 is the CD-ROM, the program goesto a step S9.

Since the type of CD-Audio includes the CD-extra, the CD-extra isdiscriminated from the CD-Audio. Therefore, at the step S6, it isdetermined whether the CD-Audio has the single session or themultisession by the address bit in the TOC of the first session. If theCD-Audio has the single session, the CD-Audio is identified. The programgoes to a step S7 where the CD-Audio reproducing program 3 is activated.Thus, a previously selected music (for example, first music) in theCD-audio is reproduced.

If the CD-Audio has the multisession at the step S6, the CD-extra isidentified. The program goes to a step S8 where a CD-extra reproducingprogram is activated, which will be described hereinafter.

On the other hand, when the CD-ROM is determined at the step S5, sincethe CD-ROM includes the photo-CD and the video-CD, it is necessary todiscriminate the type of CD-ROM. Therefore, at the step S9, it isdetermined whether the CD-ROM has the single session or the multisessionby the address bit in the same manner as the step S6.

If the CD-ROM has the multisession, the CD-ROM is supposed as thephoto-CD. The photo-CD is discriminated from the CD-ROM by a directoryname. The program goes to a step S10 where the reading section 7 isoperated to read a VTOC (Volume Table of Contents) in an LSN16 (physicaladdress 00:02:16) of the last session. Since the VTOC comprises a PVD(Primary Volume Descriptor) which has a pointer for a root directory forthe directory name, the VTOC is read. At a step S12, the directory namein the root directory is obtained.

If the CD-ROM has the single session at the step S9, the CD-ROM issupposed as the video-CD. Thus, as aforementioned, the video-CD isdiscriminated by the directory name. The program goes to a step S11where a VTOC in an LSN16 of the first session is read by the readingsection 7. At the step S12, the directory name in the root directory isobtained.

At a step S13, directory names in the respective root directories areretrieved.

If a directory name “VCD” is found out, the video-CD is identified. Theprogram goes to a step S14 where the video-CD reproducing program 5 isactivated.

If a directory name “PHOTO CD” is found out, the photo-CD is identifiedso that the program goes to a step S15 where the photo-CD reproducingprogram 4 is activated.

If neither “VCD” nor “PHOTO CD” is found out, the CD-ROM is identified.The program goes to a step S16 where a reproducing program stored in theset CD-ROM is stored in the RAM 6 and the program is activated. If thereare a plurality of programs to be activated, one of them is activated inaccordance with selected or predetermined priority by the user.

Thus, the operability of the computer is further improved.

The operation of the CD-extra at the step 8 will be described withreference to the flowchart of FIG. 3.

In order that the CD-extra can be reproduced by an ordinary CD playerand the CD-extra can be used in a CD-ROM drive, an audio track of theCD-extra is provided in the first session, and a data track thereof isprovided in the second session.

Heretofore, when the CD-ROM drive detects a multisession CD, the lastsession (namely, data track) is read first. Since the CD player formusic can not detect the multisession CD, the first session is readfirst.

In the embodiment, since it is possible to reproduce both of the musicCD and the CD-ROM, it is more convenient for the user if one of thesessions of the CD-extra can be selected as priority reproduction.Therefore, for the activation of the CD-extra (step S8 of FIG. 2), stepsS31 and S32 are added as shown in FIG. 3.

Referring to FIG. 3, when the CD-extra is identified at the step S6 ofFIG. 2, selection information stored in the RAM 6 is read at a step S31.The selection information instructs which session should be reproducedfirst. If the selection information is “1”, priority reproduction of theaudio session is instructed. If the selection information is “0”,priority reproduction of the data session is instructed.

At a step S32, it is determined whether the selection information is thepriority reproduction of the audio session or not. If yes, the CD-audioreproducing program 3 is activated in the same manner shown at the stepS7 of FIG. 2. If not, the reproducing program stored in the CD-extra isstored in the RAM 6 and activated in the same manner shown at the stepS16.

Thus, it is more convenient to reproduce the CD-extra.

FIG. 4 shows an operation of the controller 2 for deciding the selectioninformation of FIG. 3. The deciding program is periodically operated.

At a step S41, it is determined whether the selection is requested ornot (for example, a selection request key on the display is clicked). Ifnot, the program is terminated. If yes, the display 10 is operated todisplay a selection mode at a step S42.

At a step S43, it is determined whether priority session is input by theuser or not. If yes, the program goes to a step S45 where the selectinformation stored in the RAM 6 is updated based on the input.

If not at the step S43, the program goes to a step S44 where it isdetermined whether the selection mode is canceled or not. If not, theprogram goes to the step S43 which is repeated until the selection modeis canceled.

Thus, the user can select the priority reproduction of the session ofthe CD-extra at will.

Other than the CD-extra, a CD having multisession can also be used inthe embodiment.

An automatic calling function of the related information of the CD willbe described with reference to the flowchart of FIG. 5. Such a functionis operated by the automatic calling program of the controller 2. Theoperation can be performed in parallel with the operation shown in FIG.2.

As the related information of the CD, for example of the music CD, titleof a music, list of songs, picture used on a jacket, words of song, homepage of singer, and names of singer, writer, composer and player arestored.

At a step S51, it is determined whether the CD 8 is set or not. Namely,when the CD 8 is mounted on a disc tray of the reading section 7, thereading section 7 produces a detecting signal which is periodicallydetected by the controller 2. If yes, the program goes to a step S52. Ifnot, the program is terminated.

At the step S52, identification information such as the TOC informationand the type of CD is obtained. In the TOC information, information suchas minute, second and frame number is used for identifying the CD. Theinformation of the type of CD, which is described in FIG. 2, is used forretrieving data at a high speed.

At a step S53, data of the retrieval table 18 a stored in the database18 is retrieved for retrieving a keyword (for example, name of artist ortitle, if the CD 8 is the music CD) corresponding to the identificationinformation.

FIG. 6 shows an example of the retrieval table 18 a. Here, the table ismade in accordance with the type of CD, thereby reducing work-load ofthe retrieval.

Furthermore, it is not necessary to correspond one piece ofidentification information to one keyword. For example, theidentification information 1 may correspond to a plurality of keywords1, 2, and reversely, a plurality pieces of identification information 2,3 may correspond to the keyword 3.

The database 18 can be made by the user by manually inputting data, orobtained by other reproducing medium (for example, a CD which stores adatabase).

Furthermore, information on-keyword can be stored in the CD. Forexample, a CD text of character information stored in a sub code can beused as a keyword. In this case, the process at the step S53 is omitted.

The server 13 has a keyword retrieving section 16 having a databaselarger than the database 18. The server 13 is accessed by theidentification information, thereby obtaining keywords which are storedin order corresponding to the identification information. Thus, thedatabase shown in FIG. 6 is made.

At a step S54, it is determined whether the keyword is obtained or not.If yes, the program goes to a step S55. If not, the program goes to astep S59.

At the step S55, an address of the keyword is retrieved.

FIG. 7 shows a retrieval table. As the table shown in FIG. 6, it is notnecessary to correspond one keyword to one address. For example, thekeyword 1 may correspond to a plurality of addresses 1, 2, andreversely, a plurality of keywords 2, 3 may correspond to the address 3.

As aforementioned, the database can also be made by the user by manuallyinputting data, or obtained by other reproducing medium. Furthermore,information on keyword can be stored in the set CD. In this case, theretrievals of keyword and address are omitted.

The server 15 having an address retrieving section 17 is accessed by theidentification information, thereby obtaining addresses which are storedin order corresponding to the keywords. Thus, the database shown in FIG.7 is made.

AT a step S56, it is determined whether the corresponding address isobtained or not. If yes, the program goes to a step S61 where therelated information corresponding to the obtained address is displayedon the display 10.

The address is used as an address for the home page used in theInternet.

The related information such as a home page is obtained by accessing theserver 14 for the retrieved address through the channel 12.

Furthermore, it is possible to obtain the related information of thecorresponding address from a CD-ROM which stores the related informationwithout using the network.

At the step S56, if the corresponding address is not obtained, theprogram goes to a step S57 where the display 10 is operated to display arequest to the user for inputting an additional keyword.

FIG. 8 shows an example of information for the request on the display10.

At a step S58, it is determined whether a data of additional keyword isinput by the user or not. If yes, the program returned to the step S55.If a data of cancel is input, the program is terminated.

On the other hand, at the step S59, since the keyword is not obtained bythe database, the server 13 having the keyword retrieving section 16 isaccessed so as to transmit the identification information. The server 13retrieves a corresponding keyword which is applied to the computer 1.

At a step S60, it is determined whether the corresponding keyword isobtained or not. If yes, the program goes to the step S55. If not, theprogram goes to the step S57.

Thus, it is possible to automatically display the related information.

In the embodiment, although the address is retrieved by the database 18,the address may be retrieved by the server 15 having the addressretrieving section 17, as aforementioned. In this case, the computer 1transmits the keyword to the server 15 for requesting the retrieval ofthe address.

If the keyword is retrieved by the database in the computer 1 at stepsS53, S54, and if the address can not be obtained, the retrieval of theaddress is requested to the server 15 having the address retrievingsection 17 for obtaining the corresponding address.

Furthermore, it is possible to retrieve the keyword only by the server13 having the keyword retrieving section 16 without using the database18. Alternatively, all of the keyword and the address can be, retrievedby the servers 13 and 15. In the former case, the computer 1 transmitsthe identification information to the server 13 for requesting theretrieval of keyword. In the latter case, the computer 1 transmits thekeyword to the server 15 for requesting the retrieval of address.

In the embodiment, the keyword is retrieved by the identificationinformation, and the address is retrieved by the keyword. Thus, thegeneral retrieval functions of the servers 13 and 15 can be easily used.

As shown in FIG. 1, if a server 20 having a retrieving section 19 isprovided for directly retrieving the address by the identificationinformation, the address is directly retrieved without retrieving thekeyword.

FIG. 9 shows another embodiment of the automatic calling function ofFIG. 5 in which the address is directly retrieved by the identificationinformation. The operation may be performed in parallel with theoperation shown in FIG. 2

At a step S91, it is determined whether the CD 8 is set or not in thesame manner as the step S51 of FIG. 5. If yes, the program goes to astep S92. If not, the program is terminated.

At the step S92, the identification information such as the TOCinformation and the type of CD is obtained in the same manner as thestep S52 of FIG. 5.

At a step S93, data of the retrieval table 18 a stored in the database18 is retrieved for retrieving an address (for example, an address ofthe home page of the singer, if the identification information is forthe music CD) corresponding to the identification information.

FIG. 10 shows a retrieval table. As aforementioned, the table is made inaccordance with the type of CD, thereby reducing work-load of retrieval.Furthermore, it is not necessary to correspond one piece ofidentification information to one address. For example, theidentification information 1 corresponds to a plurality of addresses 1,2. Reversely, a plurality pieces of identification information 2, 3correspond to the address 3.

As aforementioned, the database can be made by the user or obtained byother reproducing medium. It is also possible to further store theinformation on address in the other reproducing medium. In this case,the process at the step S93 is omitted.

The server 20 is accessed by the identification information, therebyobtaining addresses which are stored in order corresponding to theidentification information. Thus, the database shown in FIG. 10 is made.

AT a step S94, it is determined whether the corresponding address isobtained or not. If yes, the program goes to a step S99 where therelated information corresponding to the obtained address is displayedon the display 10.

In order to display the related information such as a home page, thebrowser program is activated to access the server 14 for the retrievedaddress through the channel 12. The obtained information is reformed tobe displayed on the display.

As aforementioned, it is possible to obtain the related informationcorresponding to the address by the CD-ROM which stores the relatedinformation.

If the corresponding address is not obtained at the step S94, theprogram proceeds to a step S95 where the server 20 having the retrievingsection 19 of a large database is accessed so as to transmit theidentification information. The server 20 retrieves the correspondingaddress which is applied to the computer 1.

At a step S96, it is determined whether the corresponding address isobtained or not. If the address is obtained, the program proceeds to thestep S99.

If not, the program proceeds to a step S97 where the display 10 isoperated to display a request to the user for inputting an additionalkeyword or address.

At a step S98, it is determined whether a keyword or address is input bythe user or not. If the keyword is input, the program is returned to thestep S93. If the address is input, the program proceeds to the step S99.

Thus, the related information can be automatically displayed.

It is possible to retrieve the address only by the server 20 having theretrieving section 19 without using the database of the computer.

In place of the CD, other reproducing medium such as a DVD may be used.

In accordance with the present invention, when the CD is set on theplayer of the computer, the related information of the CD isautomatically obtained. Consequently, it is possible to increase theoperability of the computer.
